The current project seeks to meet these needs by building a user-informed guided self-help version of Acceptance and Commitment Therapy (ACT), an evidence-based transdiagnostic therapy that has been found to effectively treat a range of mental health problems by targeting experiential avoidance, the tendency to avoid unwanted emotions and negative thoughts.After the program has been built in the first stage of the study, the investigators will then test this program at several CCCs throughout the country. An ACT program would provide a means of implementing effective treatment for the range of problems encountered in the CCC setting, while the online guided self-help format would reduce counselors' workload for each client, improving cost effectiveness and reducing waiting lists. This product would both treat students through a series of self-help modules and train CCC counselors in how to implement the guided self-help ACT intervention.
